How do I port Foward for my internet radio?

[haloflooder]

I have been trying to port forward to my wireless laptop and the portchecker.exe said that my port 8000-8001 is open but when I type in my ip address and port number the server page won't come up... http://138.88.47.134:8001/. I'm using Icecast2 and i have followed some instructions but nothing...
BUT when i do http://localhost:8001/ i can go to my server page... when i put in http://localhost:8001/IZRBoD.ogg into my music player i can listen my internet radio... but if i do http://138.88.47.134:8001/IZRBoD.ogg i just get a message error that the page will not connect...
I have
Modem: Westell 2200
Wireless router: Linksys WRT300N
Laptop OS: Windows XP

I have been looking at other forums and such but it didn't help me...

I'm trying to get my internet radio to work so i can listen to the music elsewhere and so other people can enjoy it also
